[Resolved]  Vodafone India — error 50

Address:

70A Dr. Lal Mohan Bhattacharya road kolkata - 14, Kolkata, West Bengal, 700014

Since 4-5 days i'm not able to send ans sms messages to anyone i've been getting the "error 50" and "not sent" prompt... And there's no response from vodafone on this i've mailed them the problem with an automated email response from them as a reply. I'm very dissatisfied with this please help me resolve this issue. Thus is not acceptable from such a telecommunications company like vodafone which is used globally. Vodafone should also work on getting its connectivity issues as i'm living in central kolkata where i'm having issues connecting to the 4g network i'm using hotspot as the carrier internet is pretty weak here. Please resolve this issue
Would be really glad
Thank you
